Japanese Beetle populations are on the rise in the Door County area, posing a threat to household, garden, and agricultural plants. The invasive species eats the leaves of a wide variety of plants, and in larger numbers can strip a plant bare to the stem. UW-Extension Agriculture Agent Annie Deutsch says that to manage Japanese Beetle populations and prevent major damage, growers should get the bugs off of plants in the morning.
Deutsch said using this method in the early morning prevents the bugs from attracting more beetles to the plant for feeding.
Japanese Beetles have been present in the US for decades, but until this summer, the pest hasn’t posed a major threat to the Door County area. Deutsch said concerned growers can find guides on UW-Extension’s website for controlling Japanese Beetle damage tailored to the type of affected plant, and she added that there are resources for many other horticulture-related problems and projects available as well, from pest and disease information to canning and harvesting guides.
